OptiCoat Jet coating provides very uniform and skipfree coating quality. It gives the best possible surface smoothness compared to any other coating method.

Sizer roll covers

The film sizing and film coating process plays a critical role in determining both the strength and appearance of paper and board. As these processes are performed inline on the paper machine, they have a direct impact on machine efficiency, runnability, and final product quality. This places exceptionally high demands on sizer roll covers used in board and paper making.

Sizer consumables

Sizer consumables play an important role in film sizing and coating. When you choose products that are optimized for your machine and process, you chieve outstanding paper quality, maximized production capacity and a stable process. Our consumables have excellent wear resistance – meaning less downtime and fewer consumables used, and, thus more production and lower costs.
